23۞ وَقَضىٰ رَبُّكَ أَلّا تَعبُدوا إِلّا إِيّاهُ وَبِالوالِدَينِ إِحسانًا ۚ إِمّا يَبلُغَنَّ عِندَكَ الكِبَرَ أَحَدُهُما أَو كِلاهُما فَلا تَقُل لَهُما أُفٍّ وَلا تَنهَرهُما وَقُل لَهُما قَولًا كَريمًا(Saheeh International)And your Lord has decreed that you not worship except Him, and to parents, good treatment. Whether one or both of them reach old age [while] with you, say not to them [so much as], "uff,"1 and do not repel them but speak to them a noble word. An expression of disapproval or irritation.
